Dear Sir,
I am a mechanical design engineer with a few years of experience into 3D modeling using autocad and 3ds max and photorealistic rendering.
I worked on a similiar jobs, and if you give me a chance to work with You, I will provide You 3D models with perfect topology and high quality renders, also You will receive .usdz, .glb, .gltf files so You can use it in AR.
If You have any question feel free to ask.
Best regards.
